This will not affect existing simulations because SO4 would be overwritten with MAM4 aerosols anyway. But if MAM4 aerosols will not overwrite GEOS-Chem SO4 in proposed changes, then SO4 must be scavenged (similarly to gas) as a bulk tracer by Neu.

Hi @lizziel , I just merged up to latest version of CAM and lifted the draft flag. Please feel free to review the code. Thanks! |

I approved this and plan to bring it into the |

Actually I do not need to update the deposition file since SO4 is already included in the one I use for 14.3. |

This will change SO4 to be deposited using Neu (as gas) instead of as aerosol as there's some mass conservation issues when mapping back from MAM4 to the GEOS-Chem bulk tracers. Thus the gas dry/wetdep list now includes the GEOS-Chem bulk
SO4tracer.It is ok to keep the
so4_aXtracers inaer_dry/wetdep_listsince the changes from within MAM will be ignored bychemistry.F90.The proper way to deal with the aerosols is just to have a MAM implementation in GEOS-Chem...
